영어 초록
The deflection of the vertical and the geoid height in the southern part of the Korean peninsular were computed from gravity anomalies by the application of the Fourier and Bessel-Fourier series. The deflection of the vertical computed from free-air anomaly has highest values of 7∼8$quot; around the central part of the Taebaek and Sobaek Mountains. The general direction appears to be nearly perpendicular to the NNE-SSW direction of the general tectonic structure of the peninsular. The geoid height increases to the south-east direction and the difference on the peninsular is about 3 m. The undulation of the Bouguer geoid appears to be correlated with the crustal thickness, having highest values on the eastern and southern coasts. The geoid height computed by using the geopotential coefficients up to the 16th order obtained from the spherical harmonic analysis of the satellite data shows similar trend of increase but much higher value than that of free-air geoid.
